Shigaraki, the Great Decay

When Shigaraki enters the battlefield, distribute
X -1/-1 counters among any number of target
creatures, then proliferate twice.
{b/r}{b/r}{b/r}: Shigaraki gains your choice of infect,
poisonous 2, toxic 2, or deathtouch.
Light: Who the Hell is this guy?!...
Ryuk: Looks like he's your competition.
Light: Damn you, shinigami!
